The apartment is exactly as described. It is really new and very clean. There are towels, linen and toiletries. There is also a HDMI cable to the massive TV which came in pretty handy during the 10pm curfew. We did not meet our host but she kept in great contact throughout. She was also especially brilliant when we had confusions about our day of arrival and was super laid back about the whole thing. We will be returning to Bangkok in the future and would definitely use this apartment again. I would recommend it highly.
Just a small P.S. the apartment is at the end of a small road/alley way which could seem a bit disconcerting to a few - but it is a nice little area, the neighbours are friendly and helpful and it is also quiet at night.
